3D Laser Scanning Modeling and Application on Dazu Thousand-hand Bodhisattva in China

A groundbreaking application of high-resolution 3D laser scanning has revealed critical insights into the preservation status and restoration potential of the Dazu Thousand-hand Bodhisattva Statue, a UNESCO World Heritage Site renowned as 'the Gem of World’s Rock Carving Art.' This innovative method overcomes limitations of traditional plane surveying by capturing superfine 3D models from cloud points, exposing localized damage that is otherwise difficult to document. The analysis provides actionable data for restoration efforts, including 3D statistics and thematic maps, while also offering suggestions for shape restoration. Published in The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, this study demonstrates the transformative potential of laser scanning technology in heritage conservation.
